Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A communication method for identifying packet flows based on predetermined rules and processing packets belonging to identified packet flows, the communication method comprising: setting, by a setting apparatus, in two first nodes, a plurality of first rules that identify a plurality of packet flows, respectively; and setting, in a second node, arranged between the two first nodes, a second rule that identifies the plurality of packet flows as a group, wherein the plurality of packet flows are flows between the two first nodes via the second node, and when the first and second nodes receive an unknown packet, the first and second nodes request the setting apparatus to set the corresponding first or second rule, and first nodes process a received packet based on the set first rule, and the second node processes a received packet belonging to one of the plurality of packet flows based on the set second rule.
A communication method identifies and processes packet flows based on rules. A setting apparatus configures two "first nodes" with multiple "first rules," each identifying specific packet flows. A "second node," positioned between the two first nodes, is configured with a "second rule" that groups these packet flows together. The packet flows travel between the two first nodes via the second node. If a first or second node receives an unknown packet, it requests a rule from the setting apparatus. First nodes then process packets based on their specific first rules, and the second node processes packets belonging to the grouped flows based on the second rule.
